WIRE BAIL-EAR.

Application filed July 25, 1914.

To all whom it may concern:

Be it known that I, GEORGE W. KNAPP, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Wire Bail-Ears, ofwhich the fol lowing is a specification.

This invention relates to an improved bail ear for sheet metal vessels and has reference to a metal ear of exceedingly simple and cheap construction and which is particularly adapted for attachment to a metal vessel by welds electrically effected.

The invention is illustrated in the accompanying drawing wherein,

Figure 1, shows the improved ear at tached to the wall of the vessel and also shows a bail eye engaged therewith. Fig. 2, illustrates the detached ear in side elevation. Fig. 3, shows the contact face side of the ear in elevation. Fig. 4:, illustrates the ear in top plan view, and Fig. 5, shows an enlarged cross-sectional detail through the contact feet of the ear.

Referring to the drawing the numeral 6, designates the loop of the ear which is formed of wrought iron wire that is round in cross-section and has substantially horizontal legs 7 and 8. This wire is cut from a strand into suitable lengths and the opposite ends thereof are split in a central longitudinal direction for a sufficient distance to enable the two divided ends to be turned or bent laterally so as to form laterally-extending feet 9. As both ends of the length of wire are split and then spread apart the ear will have four feet. The wire feet are then subjected to die pressure to form flattened inner and outer faces 10 and 11, respectively and during this flattening operation a projection 12, is produced on the inner face 10, of each foot. In many instances the ear is to be attached to a vessel whose wall has a taper or curve between the top and bottom, and as it is desirable that the legs 7 and 8,

be substantially parallel when the ear is attached to a vessel said legs are preferably, but not necessarily, of unequal length, as clearly shown in Fig. 2, of the drawing. By forming the ear of round wire that has been cut from a strand into short lengths and then splitting the two ends of said short lengths so that the metal at opposite. sides of the split may be turned laterally in opposite directions from the terminals of the splits, I form the feet, and an exceedingly cheap and strong ear is thus produced, in the manufacture of which there is no waste of material.

particularly desirable because the car may be presented to the wall 18 of the vessel to which it is to be attached, with the projections 12, in contact with said wall and suitably designed electrodes may be pressed against the outer faces 11, of the feet directly opposite the projections on the inner side and the pressure and electric current will be localized at the points of contact and thereby eflect a rapid welding of the ear to the vessel wall. A11 ear thus constructed will form a rigid connection with the vessel wall and will afford a smooth rounded surface for the engagement of the eye 14:, of a wire bail 15, as shown in Fig. 1 of the drawmg.

Having thus described my invention What I claim is,-

A bail ear formed of wire that is round in cross-section each end of the wire being split longitudinally and laid back from opposite sides of the split, said laid-back portions being flattened and each laid-back flat portion having a projection thereon.

In testimony whereof I affix my signature in presence of two witnesses.
